Sanders' Pacifist Past Troubling

I'm a lifelong Democrat and supporter of Hillary Clinton for the presidency. I believe she is the most knowledgeable and qualified candidate in the entire field.

If Bernie Sanders wins the nomination I'll support him, but one thing troubles me: Sanders' application for conscientious objector status during the Vietnam War. As a former army officer and Vietnam veteran, I wonder if that history might color his role as commander in chief.

Conscientious objection is strongly personal in nature, being predicated on an individual's core beliefs. Sanders is obviously very passionate about his political policies and we know his stance on Iraq and our involvement throughout the Middle East. Would his former pacifism be of any great consequence?
